Amsoil vs. Redline

UberWRX · Jan 5, 2003

Hi, guys!

This shouldn't be too controversial a question (yeah, right!), but do you believe that Amsoil Series 2K 0W-30/3K 5W-30 and Redline 5W-30/10W-30 are fairly comparable oils in terms of quality? I've been reading the posts here for a while, and it seems like Amsoil gets more attention; particularly when it comes to ragging on their marketing practices.

Anyway, I have a turbo-charged 4-banger that is going to be receiving some serious performance mods in the future. Performance AND protection are crucial.

Thanks!

I think theres an analysis on Redline 5W40 used in a turbo in analysis section. Pretty impressive IMO.

Bashing Amsoil's marketing is a favorite past time around here, it seems.

I would actually give the edge in wear protection to Amsoil over Redline. Most of the Redline results have hardly been spectacular, especially for something that costs $8.95/quart. The notable exception would be the results that someone posted from their 5W-40 that sprintman mentioned.

Maximum performance seems to be Redline's niche, so depending on which you wanted more would determine which brand was for you.

My prediction:
There will be 30 replies here by morning

I guess everyone was sleeping, as there were no more replies overnight!

We haven't seen enough Redline analysis reports on here to say that Amsoil is better or Redline is better. I do believe Redline is designed more for hard driving in mind though, while Amsoil tries to gear their oil for longer intervals.

I wouldn't go into a US vs. Them catagory, as I really think you are splitting hairs.

My vote would go to whichever you can find the easiest/cheapest.

Also I wouldn't hesitate to through the Amsoil 10w30 ATM in the mix if you are looking for something a little less expensive. It is especially developed for turbo applications.

Though if it were mine I would use the Series 2000 0w30.

Anyhow good luck.

I use the Amsoil 10W30 in a twin turbo and it does fine via analysis. However, short drains as I use 5000 miles or one year. If this is a manual transmission I highly recommed the RedLine gear oils over Amsoil especially in cold weather shifting.

I think that Subaru still recommends 5w-40 or 10w-40 grades for "Severe Service" use, so I'd start with either the Amsoil 10w-40 or this new Redline 5w-40. I have quite a bit of experience with the Amsoil product in turbocharged VW's and it holds up very well. Recent oil analyses of the Redline 5w-40 have been impressive as well ....

If anyone has a spec sheet on the new Redline 5w-40, please e-mail me a copy at [email protected] ....

I've been trying to no avail to find out more information concerning Redline 5W-40. If anyone could help out, please email me at [email protected].

Thanks,

Not what you asked about but if your car recommends a 5W40 synthetic consider Mobil Delvac 1. It is a fine oil at a reasonable price.

I contacted Red Line and received the following response:

Q: Do you carry an SAE 5W-40 version of your engine oil?

A: Yes, Red Line makes a 5W40 street engine oil.

Q: Must be new since no info on your web site?

A: The 5W40 has been available for about 6 months but isn't listed on the web site.

I requested a PDF version of their spec sheet and got one. Here's the pertinent info:

API Service Class = SL/SJ/SH/CD/CF (Gas/Diesel)
Viscosity Grade SAE = 5W-40
Vis @ 100C, cSt = 15.1
Vis @ 40C, cSt = 94
Viscosity Index = 170
CCS Viscosity, Poise = 55 @ -30C
HTHS Vis, cP @ 150C = 4.6
Pour Point, C = -45
Pour Point, F = -49
Flash Point, C = 250
Flash Point, F = 480
NOACK Evaporation Loss, 1 hr @ 482F (250C), % = 6

I can send anyone the pdf if they want it. By the way, this spec sheet also lists a 5W-20 oil as well.
